A configuration is provided in which a touch roll 4 having a length extending over the entire length in the paper width direction is provided on a rear side of a winding unit I on which the roll 3 is formed. The above-mentioned touch roll 4 is always brought into contact with the outer peripheral surface of the paper roll 3 at a required nip pressure over the entire length in the paper width direction, and the paper sheet 2 is wound up while being restrained by the touch roll 4. At this time, if the winding of the paper sheet 2 is continued, the paper roll 3 becomes thicker. Therefore, as shown in FIG. 9, the position of the spool 1 in the winding section I is fixed and the touch roll 4 is moved. For roll-up of paper roll 3 As shown in FIG. 10, the position of the touch roll 4 is fixed, and the position of the spool 1 in the winding unit I can be moved according to the thickness of the paper roll 3 as shown in FIG. There is something.

[0004] In the case of the winding device having a fixed winding portion position shown in FIG. 9, the winding portion I includes a pair of left and right spool supports 5.
At the take-up position, both ends of the spool 1 are rotatably supported via bearings, so that a fixed-position rotation drive device (not shown) can be detachably connected to one end of the spool 1. The bearings at both ends of the spool 1 are received at the front sides of the left and right spool supports 5, and the loading of the spool 1 onto the spool support 5 and the winding of the paper sheet 2 from the spool support 5 are completed. In this configuration, a spool transfer device 6 for unloading the paper roll 3 is installed.
On the other hand, at a position behind the winding unit I, a winding hardness adjusting unit II is configured to be movable in the front-rear direction.

The touch roll 4 extending over the support frame 5 is disposed so as to face the spool 1 on the spool support base 5, and the fulcrum 16 a
Pressure lever 16 attached so that it can swing around
The touch roll 4 is moved in the front-rear direction by swinging the pressure lever 16 about a fulcrum 16a by a fluid pressure cylinder 17 such as an air cylinder. 5. The position of the touch roll 4 can be finely adjusted with respect to the spool 1 on the support frame 5, and the touch roll 4 can be moved in the front-rear direction integrally with the support frame by the rodless cylinder 11. 11 for controlling the position of the support frame 9 in the front-rear direction and the hydraulic cylinder 1
By finely adjusting the front and rear positions of the touch roll 4 by the touch roll 7, the touch roll 4 can be brought into contact with the surface of the paper sheet 2 to be wound around the spool 1 at a required nip pressure, and the winding hardness can be adjusted. It is like that. Furthermore, if the angle between the surface of the paper roll 3 formed by the deep entry angle of the paper roll 2 into the touch roll 4 and the paper roll 2 to be newly wound is large, the paper roll 2 accompanies the traveling paper roll 2. The air
Since it is easy to invade between the paper sheet 2 and the outer peripheral surface of the paper roll 3 to cause a winding deviation, the touch roll 4
A guide roll 18 is rotatably installed at a front end inside the upper part of the support frame 9 above the guide frame 1.
The paper sheet 2 wrapped around the paper roll 8 is directed substantially vertically downward and then guided to the touch roll 4.
The angle at which the outer peripheral surface of the paper roll 3 and the paper sheet 2 to be newly wound up is made smaller by making the angle of entry of the paper sheet 2 into the taper shallower.

An expander roll 21 provided on the upper side of the guide frame 21 guides the paper sheet 2 supplied to the winding device from the rear at an upper position on the rear side of the support frame 9.

Therefore, when the paper sheet 2 is wound by using the above-described winding device, first, the arrangement of the support frame 9 in the front-rear direction is adjusted by the driving device 12 and the operation amount of the fluid pressure cylinder 17 is adjusted. Is adjusted, the touch roll 4 is brought into contact with the outer peripheral surface of the spool 1 on the spool support base 5 at a required nip pressure. In this state, the spool 1 is rotationally driven by the rotary driving device, and the guide roll 21 is rotated. And 19, the paper sheet 2 guided along the expander roll 20 and the guide roll 18 in order as shown in the figure is taken up, and as shown by a two-dot chain line in FIG.

Instead of being configured to be movable, a supporting frame 9 fixed on a support base 8 and a take-up unit I being fixedly mounted on a spool 1 on a spool support 5 are driven by a rotary drive device. Instead of the configuration shown in FIG. 9, a rotary drive device that can move in the front-rear direction integrally with the spool 1 is detachably connected to the spool 1. The paper sheet 2 guided by the
Is wound on the spool 1 in contact with the required nip pressure, and when the paper roll 3 to be formed becomes thick as shown by the two-dot chain line in FIG. The spool 1 and the rotary drive device are moved forward by a moving mechanism (not shown) by the increased amount, so that the touch roll 4 is always in contact with the outer peripheral surface of the paper roll 3 at a required nip pressure. 2 is performed. Thereafter, when the diameter of the paper roll 3 reaches a predetermined size, the rotation drive device is stopped, the spool 1 is removed from the rotation drive device, the paper roll 3 is carried out by the spool transfer device 6, and then a new spool 1 Is loaded onto the spool support 5, and the spool 1 is connected to the rotation drive device returned to the initial state, and the paper sheet 2 is wound up by repeating the same operation as described above.

[0009]

However, in each of the above-described conventional winding devices shown in FIGS. 9 and 10, the winding speed of the paper sheet 2 is increased in order to speed up the processing by the super calendar. If you try to speed up
As shown by dashed lines in FIGS. 9 and 10, the air 22 accompanying the running paper sheet 2 and the air 23 accompanying the outer peripheral surface of the rotating paper roll 3 increase in speed. The paper sheet 3 enters between the outermost peripheral portion of the paper roll 3 and the paper sheet 2 that is newly wound up while being restrained by the touch roll 4, and is accumulated between layers of the paper sheet 2. There is a problem that winding deviation and defective winding hardness occur.

Accordingly, the present invention can suppress the air accompanying a traveling paper sheet or a rotating paper roll from entering between layers of the paper sheet even if the winding speed is increased.
An object of the present invention is to provide a winding device that can reduce the risk of poor winding hardness or occurrence of winding deviation.

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, the present invention provides a winding unit for winding a paper sheet by rotating a spool carried on a spool support at that position. Behind the support frame, a support frame is provided so as to be movable in the front-rear direction that approaches and separates from the spool, and extends at the front end of the support frame over the entire length in the paper width direction arranged so as to face the spool on the spool support base. A touch roll and a guide roll arranged in parallel above the touch roll are rotatably supported, and a paper sheet guided along the guide roll is wound around a spool on a spool support base to form a paper. When forming the roll, the touch roll is brought into contact with the surface of the paper sheet wound on the spool at a required nip pressure over the entire length in the paper width direction, and a winding operation is performed. In the winding device it has manner,
An air nozzle having an outlet formed at a required angle on the surface of the paper sheet is installed at a position near the upper side of the guide roll so as to blow air toward the upstream side in the traveling direction with respect to the surface of the paper sheet traveling along the guide roll. And guide rails extending diagonally upward and rearward on the left and right sides of the spool support base so as to extend rearward along an extension of the axial center position of the spool in a bilaterally symmetrical manner, and the surface of the paper sheet wound on the spool is fixed. In order to blow air toward the upstream side in the direction of rotation of the spool, air outlets are formed at a required angle on the surface of the paper sheet, and both ends of an air nozzle are movably attached to the left and right guide rails. Install a nozzle elevating device to move along the guide rail and follow the fluctuation of the roll diameter due to the paper sheet being wound on the spool.

The leading end of the paper sheet guided along the guide roll is attached to the spool on the spool support table, and the touch roll is applied to the outer peripheral surface of the spool at a required nip pressure over the entire length in the paper width direction. In a state where the air nozzles attached to the guide rails are closer to the outer peripheral surface of the spool and the gap is reduced, and the air is blown out from the air nozzle outlets. deep. When the spool is driven to rotate in this state, when the paper sheet is wound on the spool to form a paper roll, the air accompanying the paper sheet traveling along the guide roll is located near the upper portion of the guide roll. The air blown at a required angle from the outlet of the air nozzle installed at the surface of the paper sheet at a required angle is cut by the counter flow. Further, the air entrained on the outer peripheral surface of the rotating paper roll is cut by the counter flow of the air blown at a required angle from the outlet of the air nozzle attached to the nozzle elevating device to the outer peripheral surface of the paper roll. Therefore, it is possible to suppress the air accompanying the traveling paper sheet and the air accompanying the rotating paper roll from entering the new paper sheet winding position. Thereafter, when the winding operation is continued, the diameter of the paper roll increases, but the air nozzle provided near the upper portion of the guide roll is attached to the support frame and the relative position with respect to the guide roll does not change. For,
The air accompanying the traveling paper sheet is continuously cut. On the other hand, the air nozzle attached to the nozzle lifting device
By the above-mentioned nozzle elevating device, even if the paper roll is wound thick,
By moving the paper roll upward without changing its relative position with respect to the outer peripheral surface, the air accompanying the rotating paper roll is continuously cut.

A gap sensor is mounted at one end of the air nozzle so as to protrude from the tip of the air nozzle toward the spool on the spool support base, and the nozzle is moved up and down based on a detection signal of the outer diameter of the paper roll by the gap sensor. By having a controller that gives commands to the device,
When the gap between the air nozzle and the outer peripheral edge of the paper roll becomes smaller due to the thickening of the paper roll, the outer diameter of the paper roll is detected by the gap sensor. By operating the nozzle lifting device and raising the air nozzle until the outer diameter of the paper roll is no longer detected by the gap sensor, the gap between the air nozzle and the outer peripheral surface of the paper roll is automatically maintained at a constant size. be able to.

Further, the spool carried in on the spool support table is rotated forward while being moved forward in accordance with the thickening of the paper roll, so that the paper sheet is wound up. A touch roll provided at a front end of the support frame and extending over the entire length in the paper width direction and disposed at a front end of the support frame so as to face the spool on the spool support base; and a guide roll disposed in parallel with a position above the touch roll. When the paper sheet guided along the guide roll is wound around the spool on the spool support base to form a paper roll, the touch roll is wound around the spool. In a winding device in which a winding operation is performed by bringing the surface into contact with a required nip pressure over the entire length in the paper width direction,
An air nozzle having an outlet formed at a required angle on the surface of the paper sheet is installed at a position near the upper side of the guide roll so as to blow air toward the upstream side in the traveling direction with respect to the surface of the paper sheet traveling along the guide roll. And, guide rails extending vertically are fixed and arranged symmetrically at both left and right positions on the left and right sides of the spool support base, and both ends of an air nozzle which blows air to the surface of the paper sheet wound on the spool are connected. , So that the direction of the air outlet can be changed in the front-rear direction, movably mounted on the left and right guide rails, and a nozzle elevating device for moving the air nozzle along the guide rails is installed. The air nozzle is moved upward following the fluctuation of the roll diameter and the angular fluctuation of the outer peripheral surface of the roll due to winding In a winding device in which the winding unit is movable, the structure is such that the blowing direction is directed to the upstream side in the spool rotation direction so that air to the winding unit can be cut off. Since the air accompanying the traveling paper sheet or the air accompanying the rotating paper roll can be prevented from entering between the layers of the paper sheet to be taken, the risk of occurrence of winding deviation and poor winding hardness can be reduced. .

Further, both ends of an air nozzle which blows air to the surface of a paper sheet wound on a spool are attached to rotary actuators which are arranged so as to be coaxial with each other, and each of the rotary actuators is attached. By rotating the air nozzle in the front-rear direction by the operation of the rotary actuator, the air nozzle can be rotated by operating the rotary actuator so that the air nozzle can be changed in the front-rear direction. The blowing direction can be changed in the front-back direction.

Further, a gap sensor is attached to one end of the air nozzle so as to protrude from the tip of the air nozzle toward the spool on the spool support base, and the nozzle is detected based on a detection signal of the outer diameter of the paper roll by the gap sensor. A controller for giving a command to the elevating device, a detecting device for detecting a height position of the air nozzle raised and lowered by the nozzle elevating device, and a rotary based on a height position signal of the air nozzle issued from the detecting device. With the configuration including a controller that gives instructions to the actuator, the controller activates the nozzle elevating device based on the detection signal of the gap sensor, and automatically adjusts the gap between the air nozzle and the outer peripheral surface of the paper roll to a certain size. Of the paper roll according to the height position of the air nozzle. It is possible to adjust the angle of the air nozzle so that an angle corresponding to the circumferential surface.

The spooling device shown in FIGS. 1 to 5 is attached to the rear side of the upper end of the support frame 9 via the bracket 26, and at both left and right positions of the spool support base 5 outside the support frame 9. Similarly to the worm jack 27, the worm jack 27 is configured such that a guide block 29 movably mounted on a guide rail 28 can be moved up and down by a motor 34 via a gear box 32, a power transmission shaft 33, and a screw shaft 30. The guide rails 28 are installed so as to extend in the vertical direction, and the rotary actuators 49 are arranged inside the guide blocks 28 of the respective worm jacks 27 so as to face each other via a mounting member 52 so as to be coaxial. The rotary shaft of each of the left and right rotary actuators 49 is attached to the air nozzle of the winding device shown in FIGS. 35 by attaching the tip ends of the air nozzle 35 in the same configuration as, to allow the air nozzle 35 by rotating in synchronization with the rotary actuator 49 can vary the angle about the tip. Further, a pulse generator 50 is attached to the drive motor 34 of the worm jack 27 so that the pulse generator 50 can output a height position signal of the air nozzle 35 which is moved up and down by the operation of the worm jack 27. , The air nozzle 3
